Not everything ending with a pair of parenthesis is a function (call). In this case they are parameterized macro expansions. The macros are defined as #define __acquires(x) __attribute__((context(x,0,1))) #define __releases(x) __attribute__((context(x,1,0))) ...
The function can be used by a variable that is also declared as a constexpr: constexpr double pi = Div_Expr(22, 7); // Div_Expr() is executed by compiler, pi assigned at compile time Thus, constexpr allows for optimization possibilities where some simple computation might be performed ...
The Import mode enables BGP to import routes by protocol type, such asRIP,OSPF,IS-IS, static routes, and direct routes. The Network mode imports a route with the specified prefix and mask to the BGP routing table. This mode is more precise than the Import mode. ...
After receiving a BFD packet with theStatefield set to Init, SwitchB changes the local BFD session status to Up. The BFD session status change on SwitchA is similar to that on SwitchB. BFD Session Establishment BFD sessions can be established in either static or dynamic mode. Static and dy...
